This paper describes the sequence of Alcoa’s bauxite mining and restoration operations in Western Australia, commencing with pre-mining surveys and geological exploration through to the preparation and extraction of the bauxite ore, the restoration process, and then monitoring. These methods have changed continually since operations commenced in 1963 as knowledge improved; however, this paper only describes the current procedures.
